The Indus River Valley
sustained a Bronze Age civilization (3300–1300 B.C.) that was located on the western
Indian subcontinent. The civilization's decline may have been due to extreme climate
changes and the elimination of portions of the Ghaggar Hakra river system. Situated in
Mesopotamia, the Tigris Euphrates River Valley is often
referred to as the "cradle of civilization." Beginning in the Bronze Age, it existed
from 3100 B.C. until the fall of Babylon in 539 B.C. to the conquering Achaemenid
Empire. The "cradle of Chinese civilization," the Yellow
River (or Huang He or Hwang
Ho) Valley can trace its inhabitants to 2100
B.C. It is believed that the first examples of the ancient Egyptian civilization was
established along the Nile River Valley as early as 3150
B.C.
